Answer 1

Answer:

Chlorophyll,the green colouring matters of plants responsible for photosynthesis contains 2.68%of magnesium by mass.Calculate the number of magnesium atoms in 2.00 gram of chlorophyll. Hence, 0.054 g of Mg will contain (6.023 x 1023/24 ) x 0.054 atoms of Mg = 1.34 x 1023 atoms of Mg present in 2.00 gram of chlorophyll.
